The clocks group properties and the clock@0 node are useless, remove them
to avoid copy pasting in future device trees.

Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

The clock-frequency property became obsolete since the rework of the main
clock driver in 3.16 (see commit 27cb1c20).

It now get and uses the clock-frequency from the main_xtal node.

Having clocks grouped in a subnode is common practice, so move the crystals
under a clocks node for the at91sam9rl SoC and at91sam9rl based boards.

This adds support for:
 - SPI
 - Dataflash
 - LCD
 - i2c
 - ADC
 - Touchscreen
 - USB gadget
 - PWM

Also it switches the ds1 and ds2 leds to PWM control.
